Weaver WF28 WF28 precision colorimeter precision colorimeter is based on the International Commission on Illumination CIE relevant standards, national standards developed and produced by the National Metrology SCM certified professional colorimeter. WF28 precision colorimeter with a new import key components, carefully designed, with a precise and stable, easy to operate, easy to learn, and so affordable. WF28 precision colorimeter suitable for textile, printing and dyeing, clothing, footwear, leather, chemicals, plastics, plastics, pigments, paints, inks, printing, metal, photography, toys and other industries color quality control, color control and color analysis to sample testing, production line testing, also suitable for injection molding, printing ink, paint, painting and other secondary color. WF28 precision colorimeter 8mm caliber version is a universal colorimeter, considering all walks of life to detect the color of the generic and applicable customary methods, and consider a variety of materials in the measurement of the measurement aperture size requirements and developed. WF30 precision colorimeter 8mm caliber version of its versatility and its own sets of difference between the minimum measurement stability for businesses to make this industry, cross-color exchange offer great convenience and trustworthy and reliable sex. WF28 precision colorimeter technical parameters Model WF32 display mode CIE L * a * b * color difference formula △ E * ab lighting conditions CIE recommended way: 8 / d light blue LED excitation sensor photodiode array measuring caliber Φ8mm measurement conditions observer: CIE 10 ° measurement range L: 0 至 100 repeatability △ E <0.05 (measured 30 times whiteboard whichever deviation from the mean) the difference between the instrument station △ E <0.2 0.5 seconds interval measurement data storage capacity to store 100 to store the sample standard 20000 Lamp life battery is 5000 times greater than the 1.6 million five-year measurements TFT color screen 2.8inch @ (16: 9) B-type interface -USB RS-232: The baud rate 115200bps operating temperature range 0 ° C ~ 40 ° C ( 32 ° F ~ 104 ° F) Storage Temperature Range -20 ° C ~ 50 ° C (-4 ° F ~ 122 ° F) and humidity range relative humidity below 85% non-condensing Dimensions 199x68x90 mm Weight 700g Packing size 390x220x340 mm Standard accessories AC adapter optional accessories advantages of lithium micro printer manual powder test kit WF series colorimeter built whiteboard: boot corrected himself, without manual correction, fast and convenient, but not because of the pollution caused by the school are not allowed whiteboard trouble. Measuring port positioning function: more direct and more accurate positioning, and some equipment used in window positioning, inconvenient, some with camera positioning, but the focal length are not allowed to cause excessive exposure see the goal, but requires a lot of power consumption caused by the start of measurement data disorders. 2.8-inch color screen: font large, clear display. Operation key surface: simple, clear, a look will be. Graph display technology parameters, color emulation, very intuitive. High precision: repeatability up to 0.05, and most in fact, between 0.01-0.03. With spectral color measurement instrument of LAB values ??are very close, unanimous majority of the value. Component values ??are basically the same. Portable design, the fuselage is more stable, not leaked measurement, measurement data is more accurate and reliable. Power: You can use the power adapter, as well as high-capacity polymer battery, a charge can be used 6000-8000 times. Accept custom: The company has a strong R & D team can customize their own instrument to identify the color according to customer requirements. While providing color measurement solutions. Number of invention patents: The company has six patents variety of measurement modes, three caliber to choose from, there are five color space. Moderate size and weight of the instrument, no imported equipment so heavy, heavy solid than other brands made in China. Feel very good. The appearance of generosity beautiful, beautiful lines, colors calm. Weaver colorimeter more information from the official website: http: //www.wavegd.com
